Dana J. Boente, Acting United States Attorney for the Eastern District of Virginia, and Valerie Parlave, Assistant Director in Charge of the FBI’s Washington Field Office, made the announcement after the plea was accepted by United States District Judge Liam O’Grady.

Wolberg was indicted on August 22, 2013, by a federal grand jury on charges related to computer hacking. Wolberg faces a maximum penalty of 10 years’ imprisonment when he is sentenced on April 11, 2014.

According to the indictment and a statement of facts filed with the plea agreement, Wolberg formerly worked as a systems administrator for a company identified as Company A, a cloud-computing services provider headquartered in the Eastern District of Virginia. After resigning, Wolberg continued to enter the networks of Company A for the purpose of damaging its servers, its reputation, and its business. From about March 16, 2012 through about August 1, 2012, Wolberg encouraged Company A’s customers to leave and secretly logged into Company A’s server to issue a shutdown command to a key data server. As a result, he shut down Company A’s customer networks, making key information—including that of hospitals responsible for surgery and other urgent patient care—unavailable for at least several hours. Wolberg caused hundreds of thousands of dollars of damage as a result.

This case was investigated by the Federal Bureau of Investigation. Assistant United States Attorney Alexander T.H. Nguyen and Trial Attorney Richard D. Green, on detail from the Justice Department’s Computer Crime and Intellectual Property Section, are prosecuting the case on behalf of the United States.
